MAYBE he’s spent too much time in “The City.” Whitney Port and four gussied-up girlfriends spent more than 30 minutes battling to get into hot club Winston’s in LA last weekend. A witness said, “The doorman clearly hadn’t seen ‘The Hills’ or ‘The City’ and was not impressed by her. Port seemed more embarrassed every time another group of girls were let in before her.” She eventually got through when someone recognized her and pointed her out to the doorman.
